Most founders I meet have already decided to raise a round before they have asked themselves a simpler question: do I actually need to sell part of my company right now?

It is an easy mistake to make. The startup press celebrates raises, not the founders who avoided them. Accelerators are geared towards equity. And almost everyone whose advice you read online benefits in some way from you doing a round. I spent my career on the other side of the table, in corporate banking, sitting on the capital side of decisions about who got funded and on what terms. From there, one thing becomes obvious that is rarely said out loud to founders: equity is the most expensive money you will ever take.

This post is about the money that does not cost you your company. When it works, when it does not, and how to put it together.

Why equity is the most expensive money you will take

When you take a loan, you know exactly what it costs. A rate, a term, an end date. When you sell equity, the price is open-ended. You are handing over a percentage of everything the company will ever be worth.

A quick illustration. Say you raise £150,000 at a £1 million pre-money valuation. That is a £1.15 million post-money, so your investor now owns just over 13% of the business. If you go on to build something that sells for £10 million, that 13% is worth roughly £1.3 million. You paid £1.3 million for £150,000 of cash. No lender on earth would charge you that.

That is not an argument against ever raising. Often equity is exactly right, and I will come to when. It is an argument for being honest about what it costs, and for exhausting the cheaper options first.

The non-dilutive toolkit, and the current numbers

Non-dilutive simply means funding that does not cost you shares. For a UK early-stage founder, there are four sources worth knowing properly.

A Start Up Loan

The government-backed Start Up Loan is the obvious starting point and the most misunderstood. The headline terms:

• Between £500 and £25,000 per founder, repayable over one to five years

• A fixed rate of 7.5% a year (it rose from 6% in April 2026)

• No application fee and no early repayment charge

• 12 months of free mentoring included

• Eligibility now extends to businesses trading for up to five years, up from three

Because each founder applies personally, a two-person team can access up to £50,000, and a business can reach a combined £100,000 across founders.

One honest warning. This is a personal loan used for business purposes, not company debt. If the business fails, the obligation does not die with it. You are on the hook personally. Borrow what the plan can realistically service, not the maximum on offer.

Grants

Grants are the only money on this list that you never repay and never give shares for. Innovate UK and the wider UKRI network are the headline names, but the long tail matters more for most founders: regional growth hubs, devolved nation schemes, and sector-specific competitions, many of which are far less contested than the national programmes.

The trade-off is real. Applications are competitive, the paperwork is heavy, and timelines run to months, not weeks. Grants reward founders who can write clearly and wait. They are a poor fit if you need cash this quarter to keep the lights on.

R&D tax credits

If you are building genuinely novel technology, R&D tax relief can return real cash. The rules changed in April 2024, so ignore older guidance. Most companies now claim through the merged scheme, worth up to roughly 18.6p per pound of qualifying spend for a loss-making SME. If you are research-intensive, meaning at least 30% of your total spend goes on qualifying R&D, you may qualify for Enhanced R&D Intensive Support, worth up to around 27p in the pound.

Two things to hold in mind. It is retrospective: you spend first, then claim, so it is a reimbursement, not upfront capital. And HMRC has tightened compliance considerably, so this is one area where a specialist adviser earns their fee. Don't try to freestyle an R&D claim.

Your customers

The cheapest capital in any business is a paying customer. Annual contracts billed upfront, deposits on bespoke work, a discount for paying twelve months in advance: each puts cash on your balance sheet that you never repay and never dilute for. Early customers are far more willing to pay ahead than most founders assume. They simply have to be asked.

What non-dilutive funding cannot do

I am not going to tell you that you can build a venture-scale company entirely on loans and grants. You usually cannot, and any platform that implies otherwise is selling you something.

• It rarely replaces a round pound for pound. A £25,000 loan does not stand in for £150,000 of equity.

• Debt has to be serviced. If you are pre-revenue with no path to repayment, taking on personal debt is not brave, it is reckless.

• Grants and R&D claims are slow. Neither solves a cash emergency.

• These sources reward a certain kind of business. A deep-tech company with R&D and grant eligibility has more non-dilutive options than a consumer app that needs to spend hard on growth.

The point is not to avoid equity forever. It is to avoid selling it before you have to.

The play that actually saves you equity

Here is where it comes together. The smartest use of non-dilutive funding is not to replace your round. It is to delay it, so that when you do raise, you raise at a higher price and sell less of the company for the same cash.

Take the earlier example. You need £150,000, and today you would raise it at a £1 million pre-money, giving away just over 13%.

Now suppose instead you take a £40,000 Start Up Loan across two founders, win a £20,000 regional grant, and line up a couple of annual contracts paid upfront. That is not £150,000, but it might be six months of runway. You use those six months to ship the product and land your first real customers. With that traction, your pre-money is no longer £1 million. Say it is now £2 million. You raise the same £150,000, but this time you give away around 7%.

Same cash in the bank. Almost half the dilution. On a £10 million exit, that difference is worth roughly £600,000 to you.

That is the prize, and it is hiding in plain sight. The non-dilutive money was never meant to be the whole answer. It was meant to buy you the time to make your equity worth more.

When you do raise, make the relief work for you

When equity is the right call, and often it is, structure the round so the tax reliefs do the heavy lifting. Most early UK angel rounds are built to qualify for SEIS, which gives your investors 50% income tax relief on up to £200,000 a year, with your company able to raise up to £250,000 under the scheme in total. After that, EIS takes over at 30% relief, and from April 2026 the EIS company limits roughly doubled, so there is far more headroom than there used to be.

In plain terms: SEIS can halve the effective cost of backing you, which makes a hesitant angel far easier to convince. It deserves its own post, and it will get one. For now, just know that getting advance assurance from HMRC before you pitch, not after, is one of the highest-return hours you will spend.

So which is right for you?

A rough rule I would offer:

• Lean non-dilutive when you can reach a meaningful milestone on a modest amount, when you have a credible path to repay any debt, or when you qualify for grants and R&D relief. Every month you delay a round at a higher valuation is money in your pocket.

• Lean towards equity when you need a large amount fast, when the opportunity is genuinely winner-takes-most and speed matters more than ownership, or when the right investor brings far more than money.

Most founders sit somewhere in between, and the answer is usually a blend: a little debt, a grant if you qualify, customer cash where you can get it, and a smaller, later, better-priced equity round than the one you would have done today.

The instinct to raise is strong, and the ecosystem reinforces it at every turn. But the founders who keep the most of their companies are rarely the ones who raised the most. They are the ones who knew, each time, whether they were selling equity because they needed to, or just because everyone else was.

The figures here are correct as of June 2026. Tax reliefs and scheme terms change, sometimes at short notice, so always confirm the current limits with a qualified adviser or the relevant government page before you act.
